Glycine

Manufactured by Biosharp
Sourced in China

Glycine is a versatile chemical compound commonly used in various laboratory applications. It is the simplest amino acid, consisting of a single hydrogen atom attached to the central carbon atom. Glycine serves as a building block for proteins and is involved in various biochemical processes. Its core function is to provide a basic structural unit for the synthesis of proteins and peptides, which are essential in biological systems.

SKOV3 Cell Line Knockdown Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ovarian carcinoma SKOV3 cell lines were obtained from the Shanghai Institute of Cell Library (Shanghai, China). The small interfering RNA (siRNA) was designed and constructed as a vector (plasmid without vector and bacterial strain containing this plasmid were all produced and identified by Nanjing Moji Biological Technology Development Co. Ltd., Nanjing, China). The main reagents used were: CCK-8, IL-8, RPMI-1640 basal culture medium, double-antibody and fetal bovine serum (FBS) (both from Gibco, Grand Island, NY, USA), acrylamide, methylene acrylamide, Tris-base, ammonium peroxydisulfate, TEMED, glycine and SDS (all from Biosharp, Hefei, China). The PVDF membrane, and chemiluminescent liquid were purchased from Thermo Fisher Scientific, Inc. (Waltham, MA, USA).

EDU Staining for Cell Proliferation

Check if the same lab product or an alternative is used in the 5 most similar protocols
EdU (5-ethynyl-2′-deoxyuridine) staining enables quick and effective cell proliferation assays to accurately measure the proportion of cells in the S phase. Therefore, using EdU staining in accordance with the manufacturer’s instructions, the proliferation of pGCs was determined. After treatment with 0 mmol/L, 20 mmol/L, 40 mmol/L, and 60 mmol/L 2,5-HD for 24 h, cells were cultured in phenol red-free DMEM/F12 with 50 μM EdU (RiboBio, Guangzhou, China) staining for 2 h [23 (link),24 (link)]. Cells were then rinsed two times with 0.02 M PBS (pH = 7.2) at 5-min intervals before being immobilized for 30 min with 4% paraformaldehyde (Biosharp, Hefei, China). Following that, cells were treated for 5 min with glycine (Biosharp, Hefei, China) (2 mg/mL) and rinsed for 5 min with PBS [23 (link),24 (link)]. After 30 min of DAPI (0.5 μg/mL) (Biosharp, Hefei, China) staining [23 (link)], three rounds of PBS washing were conducted at 5-min intervals. Lastly, a Leica DM4000 BLED microscope (Leica Microsystems DM2500, GER) was used to observe the fluorescence in cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
